The Ultimate Solution for Corrosion and Rust Protection
Extend the Life of Your Trailer with Hot Dip Galvanizing
Felling Trailers’ hot-dip galvanizing process delivers long-lasting corrosion protection from demanding environments. By coating steel inside and out, galvanizing helps reduce maintenance, improve durability, and increase trailer lifespan
Whether your trailer operates in marine, industrial, municipal, or harsh winter conditions, galvanized protection helps your investment stand up to the elements year after year.
Designed for Long-Term Protection
Hot dip galvanizing provides long-lasting corrosion protection across a wide range of environments.
| Industrial use | Up to 65 years |
| Tropical Marine use | Up to 70 years |
| Temperate Marine use | Up to 70 years |
| Suburban use | Up to 85 years |
| Rural use | Up to 120 years |
The Hot Dip Galvanizing Process
Felling Trailers partners with AZZ Galvanizing to provide high-quality hot dip galvanizing for trailers and components requiring long-term corrosion protection.
The finished galvanized coating provides durable corrosion protection inside and out, helping trailer components withstand harsh environments, road salt, moisture, and demanding applications while reducing maintenance over the life of the trailer.
Step 1: Preparation
Steel components are inspected to ensure proper drainage and venting before entering the galvanizing process. This helps ensure complete coating coverage and consistent results.
Step 2: Cleaning
Components are cleaned to prepare the steel surface for galvanizing.
Caustic Cleaning: Removes oils, dirt, and other contaminants.
Acid Pickling: Removes rust and mill scale from the steel surface.
Fluxing: Prepares the steel for a strong bond with the zinc coating.
Step 3: Galvanizing
The steel is fully immersed in molten zinc at 840°F. The zinc bonds permanently to the frame, reaching interior tubular walls, tight welds, and hidden pockets to seal out rust and corrosion inside and out.
Step 4: Post-Dip Quality Inspection
The galvanized components are cleaned and carefully inspected to verify coating thickness, appearance, and compliance with ASTM specifications.

Frequently Asked Questions About Galvanizing
Hot-dip galvanizing provides long-term corrosion protection and reduced maintenance by protecting steel inside and out, even in hard-to-reach areas. The durable zinc coating resists rust, chipping, scratching, and abrasion, helping trailers withstand harsh environments, stay in service longer, and lower lifetime maintenance costs.
The lifespan of a galvanized trailer depends on the operating environment, but hot-dip galvanizing can provide decades of corrosion protection. Galvanized steel can offer up to 65 years of protection in industrial environments, up to 70 years in marine environments, up to 85 years in suburban areas, and up to 120 years in rural settings.
Yes. Hot-dip galvanizing uses 100% recyclable steel and zinc, contains zero VOCs, and incorporates recycled zinc in the production process. Process byproducts are also recycled and reused in agriculture and other industries, helping reduce waste and support sustainability.
